[Q] New phone. Best approach to root and go to ICS? (version problems?) - Galaxy S II Q&A, Help & Troubleshooting

tl, dr: brand new SG S2. Want to get CF-Root v5 CWM5, CM9, Siyah kernel 3.
I've been reading a lot of threads here lately, but I'm still confused about some things.
I'm new to android, but not so new to most concepts mentioned as I'm a linux user.
So I have a brand new SG S2 and want to root it and install CM9 (ICS) in it.
But before that, ideally I'd like to backup my phone (rom + efs). But to do that I have to flash CF-root, which itself modifies the stock kernel. So I'll lose my stock kernel.
1) Any work around to this? In linux?
My understanding is that this will get me the yellow triangle. And on CF thread he explains how to get rid of it. But the problem is that I checked the stock kernel thread here and I don't see my firmware there.
(4) Find an original Samsung signed stock kernel (preferably from the same stock firmware you have, but it's not terribly important)

My firmware is PDA: I9100BUKG2 and PHONE: I9100BUKG1.
Do I only need to care about the KG1/KG2 reference? And which one is more important the PDA or PHONE?
So for example would XWKG1 do the trick?
There is also the issue of CF-Root upgrade. For my phone only CF-Root v4.1-CWM4 is available (I have PDA *KG2 and PHONE *KG1).
2) So after I flash CF-Root v4.1-CWM4, get root, backup my phone with CWM and k-tool, can I upgrade to CF-Root v5? Or am I stuck to v4?

Other kernels
Replacing CF-Root with other kernels and vice-versa sometimes works, sometimes it doesn't. I don't have a list.
When going from CF-Root to another kernel, root will usually stay, while CWM will be lost (unless the other kernel also includes it), but there should not be issues. The CWM Manager app may remain, but probably won't do anything useful.

3) Does this means it's impossible to upgrade to CF-Root v5 or to use the Siyah kernel?
How can I solve this?
Sorry if this post is somewhat confusing, I'm a bit confused myself
Thanks for any help.

Pmed u dude
Mod or Die

1.) There are a few BUKG2 on samfirmware.com. Not sure which one your provider is though. Once you upgrade to ICS (CM9(, you can use the triangle away in the original development thread to remove the yellow triangle and reset counter (works only for ICS) so that is one option for you.
Regarding the kernel, go under settings, about phone and see what it says under kernel (KG1 or KG2).
2) Once you root and get CWM, you can just flash a different kernel with the updated CWM to get v5. You could also just install the siyah kernel from V4 as it comes with its own version of CWM.
3) You will be fine with flashing most kernels from CF-kernel. Most kernel for the i9100 in xda includes CWM or sometimes its own version of CWM.

I used zergrush exploit to root my gf her i9100 with 2.3.5. Used root explorer to grab efs directory.
Then i had root so i could use mobile odin. Now phone is on litening 4.0.3 ics rom probably still with gb bootloader.
No triangle yet
Gonna flash ics bootloader through odin and move to cm9 nightlies tomorrow.

The zergrush exploit requires
(1) make sure u have installed adb drivers for ur device

What exactly does this mean?
Do I need to install the SDK? Or do I only need the adb executable file? Or is there any SG S2 specific file that I need to download?
Thanks
EDIT: in linux it only requires setting up a udev rules file

Also went with the zergrush, and after that kTool to flash CF-root CWM kernel.

[Q] Help! Impossible to Root - SU Binary will not install (ICS / XWLP7)

Hi,
Hoping some of you guys can help me out. I've just taken ownership of an unlocked/unbranded SGSII with the following details :
Model : GT-I9100
Android Version : 4.0.4
Baseband : I900XXLPS
Kernel : [email protected]#3
Build : IML74K.XWLP7
I've flashed CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5 via Odin without any hitches. I see the warning triangle indicating the insecure kernel, busybox, cwm are installed and SuperUser app appears in my app draw. However, it seems the SU binaries just will not install... therefore no root access. Current version shows as vNull and the update option in SuperUser fails as a result.
I've tried flashing the su binary zip via clockwork recovery but it just won't install. Complains of an error with the zip and aborts with status 0! I know some threads recommend to just "keep flashing till it works" for this type of error... but I gave up after about 10 tries... there's something else going on here.
I've even tried the speedmod-kernel-s2-ics-k3-18-Odin kernel ... same problems.
Even 'S2 Root.exe' complains... ROOT ACCESS DENIED!
I've repeated all this a number of times (kernel flash counter up to about 10 now) and even done factory rest, wiped dalvik, reset data etc etc. No luck.
I've read forum after forum and I'm completely out of ideas so hoping for a hand. Even if it's just to say it can't be done for whatever reason.
For now i've just flashed back to stock samsung kernel to get rid of the warning triangle.
Any help appreciated
immedeately after flashing the CF-root, before doing anything you have to open Super SU application once for automatic binary updating...
Flash CF-root LP6 or LP8 from ODIN,
also you have options to flash other Root kernels too like Siyah..

Thanks for the reply. Just tried flashing Siyah v3.2.3 exactly the same results.
SuperUser app refuses to update binary because it can't detect/see the current version and reports it as 'vNull'. Again, no amount of manual flashing of su binary works.
flash another ICS ROM from ODIN, LP9 asian version...
then root again with CF-root, finish up headache...
small correction XWLP7 bult official android version is 4.0.3 not 4.0.4

Root is not required for ODIN flash...
Among the latest ICS official versions it is reported that DXLP9 is the stable and bugfree, normally on unbranded phones, region doesnt matter if you are using english language for setup.
you can pick the best one from this thread after reading review posts in the same thread.
http://forum.xda-developers.com/showthread.php?t=1544487
or
if you only need a rooted Rom and not require to flash any rom further from CWM, you can try any latest from this thread, these are pre-rooted odin flashable ROM with stock recovery not the CWM
http://forum.xda-developers.com/showthread.php?t=1544487
@ZACQ8 Thanks for the help on this. I always asumed you had to be rooted to flash a new rom, regardless of the method used. I guess you learn something new every day.
I've check those threads out and give things a go.
cheers
Cheers @ZACQ8
Rooted and booted
Your advice is much appreciated
Nice to know that you succeeded, thank GOD..

[Q] Assistance needed with first root of SG2 i9100

Hi guys. I have been a frequent visitor and learned alot about android and features. I am ready to root my galaxy s2 i9100
My details are :
Android version: 4.04
Model number gt-i9100
Baseband version: i9100XXLQ6
Kernal version: I9100xxlbq-cl911584
build number: IMM76D.XXLQB
I downloaded
ODIN 1.85
CF-Root-SGS2_XX_XEO_LQB-v5.6-CWM5
I am not seeing the original kernal file up for download for my version. What else do I need for my root? Is there any advice such as best method and such. Thank you kindly everyone. Mods, if I posted in the wrong section, please move my thread to the correct location.
That's all you need mate. This kernel is declared safe by Chainfire but as any 4.0.4 kernel should not be used to wipe data because of possibility of emmc cap bug rendering your phone bricked. Root with this kernel but make sure to switch to custom safe one before attempting to wipe data.
Best of luck

Essentially flashing using a 4.04 firmware will brick the phone? or is it when I flash, it will be bad to flash using a 4.04 firmware? Sooo confused.
If anyone has the steps what I should do, please tell me. I am worried about bricking.
If I root the phone, when official JB comes out, will I be able to update?
any help guys? The thread isn't very clear what do I do if I have this kernal. Do I downgrade before rooting?
Insted of flashing that Cf root kernel with Odin or Cwm, flash Siyah 4.1.5.

I actually have the same HW version in my new SGS2 and I have checked with eMMC check (downloaded from Google Play) that my chip is safe from "brick bug" :laugh:
Now the question is: which kernel to choose, CF or Siyah ? I'm planning to use CyanogenMod 10 on this phone, does kernel version matter at all in this case ?
/edit:
ROM will be either original CM10 or one of the variants (like HellyBean for example)

If GotBrickbug app by CF said your chip is safe than it shouldn't matter what kernel you use. Safe hardware.
Personally I always prefer rooting with CF kernels that match my FW version. Then if you're still unsure about the chip... flash siyah, go to advanced (while still in recovery) > reboot recovery. Then wipe data with siyah kernel just to be on the safe side. I always keep siyah 3.5.2 (the first transisiontl ics/jb kernel) for those purposes. CM10 built in kernels are all considered safe so that's the last time you'll ever be worried about it.
Best of luck, man
Thank you very much, I ran emmc check and I have a sane chip.
if I flash with the CF LBQ, what is my next step?

your phone will be rooted and u can then choose to install a custom kernel like Siyah v 4.1.5 on ur phone which gives u the latest CWM recovery thro which u can install any custom rom of ur choice(meant for i9100 though) on ur phone
Thank you very much!
If my questions seemed noobish, its because I want to be very sure. It my first expensive phone.
a question though, When samsung upgrades us to JB, will I be able to update it?

Samsung releases firmware in various regions and with varied carriers. So I bet that till it is officially released it will take time but when it does you will get OTA if your are on 'STOCK' ROM. but if you move away to custom rom then you will have to update manually.

To revert back assuming you didn't do backup before, download 4.0.4 firmware for your region on sammobile and flash it using odin.. Then to upgrade it when official update are up just hit OTA, kies, or flash it via odin the same way like you flash 4.0.4..
If you don't have idea how to flash then google it, theres plenty much tutorials out there.. hope it helps
Ohhhhhh. I get it. Flash using CF, or CM 10, use triangle app to remove warning triangle and if I need to unroot, flash with 4.04 (my region) using odin? Sound pretty simple. Am I missing any steps?

Actually I get confused myself hehe, by "Flash using CF, or CM 10" you mean flash what? The rest are ok..
Well, let's put this simple, Flash the CF-Root for your phone then you're rooted now, if you want to flash custom rom such as cm10 then flash it (the cm10 zip file to be flashed on recovery mode and don't forget to read the cm10 instruction before & after flashing), if you want to get rid of the triangle then do it with triangle away, finally to unroot and revert to stock, just flash stock firmware via odin..
Hi everyone! I just rooted my phone and it was sooo easy.
Thank you so much. Your advice and help definitely made it much easier than I though.

[Q] SGS2 root 4.0.4 vodafone UK

Hi, I recently got a galaxy s2 and have been wanting to root it. It has vodafone branding but is unlocked. I've searched everywhere and cannot find a single tutorial to root what my phone is running. I really need help.
Model number:
GT-I9100
Android version:
4.0.4
Baseband version
I9100BULP8
Build number:
IMM76D.BULPG
Any help is much appreciated.
Thanks
Me too! Anybody help please. GAZ are you out there?
If you just want to root, and not flash a custom rom, then follow method 1 here. It's really easy to do from stock recovery.
If you also want to flash a custom rom later, go here and find the correct PhilZ-cwm6 modified stock kernel to flash from stock recovery. Also very easy
That is good advice. It really is stupidly easy, just copy the zip file to your phone's memory (internal or external, doesn't matter), reboot in recovery mode, then install the zip file. That's it, your phone is rooted.
Note that once you're rooted your device is modified so OTA updates probably won't work and Kies may refuse to do firmware updates any longer.
Therefore you might consider invest in a copy of Mobile Odin Pro. That enables you to flash firmware updates straight from your phone, and to retain root during the flashing. Super.

Best option.
How can that be easier than downloading a zip file to the phone and flash it in recovery? You don't have to use triangle away that way...
Maybe Siyah kernel is better, and maybe not for a noob...
Siyah kernel is better for a noob because its universal, you don't have to match basebands
Also by the time you have downloaded the right file and put it on your phone, i'd be already rooted with siyah

4.0.3 firmware is safe, the issue exists only in stock 4.0.4 ICS and if you are on 4.0.4 ICS don't perform any type of wipe, reset etc... Flash 4.0.3 firmware or lower version's like gingerbread or any custom rom with custom kernels, also custom kernels for 4.0.4 version's are safe theoretically but i still wont recommend it because I have seen people brick their phone from CWM, so the problem is with the kernel which has eMMc cap erase command, most custom kernels don't have it, but be warned an old Siyah kernel has it so use the newest one.
For the sake of safety i recommend that you flash 4.0.3 via Odin.

Use the latest Siyah its pretty amazing, i consider Odin as the safest method, even though if you can obtain Siyah as a zip file you can do it via CWM which is also a pretty safe and easy method for noobs, if you downloaded a tar flash via Odin or Mobile Odin.

[Q] Does CF-Root fix superbrick bug?

I have a Samsung Galaxy S2 i9100 purchased in UK
Running Android 4.04
I want to upgrade to CM10.
I did the CF root as shown here http://forum.xda-developers.com/showthread.php?t=1103399
Basically used odin from my PC and flashed the device
Then I ran a superbrick-check app and it told me I have the "0x19", insane chip problem.
I'm wondering if the CF-root fixed the bug problem or if I have to take other steps before I proceed.
I'm not sure if cf root will allow it, but you need to install a custom kernel like Siyah or Dorimanx in order to wipe data safely. But before you do that, you need to make a nandroid of your current stock setup......cmiiw.....
sent from my CM10.1 powered I9100 with Tapatalk 2
CF-root kernel is like stock only with root, superSU (of course) and CWM app, i don't think Chainfire focused on fixing CWM Recovery.
So as Keith said...flash Siyah, Dorimanx or Philz. All are recommended although i use Siyah and i like it.
One of these three, read about them and decide for yourself.
Cheers.
Amen to the above you cannot wipe anything while on 4.0.4 kernel or cf-root (as warren said it only injects SU & CWM to 4.0.4 kernel).
Once you flash any other ROM you can forget about the brick bug, it's ONLY 4.0.4 related.
The only way to fix that bug is to stay away from the mentioned kernel.
